I agree MacOS feels dated, some examples: The Windows window manager is far better than the MacOS equivalent, the UI is higher quality, more consistent and more discoverable, and PowerShell is better than zsh.
I guess it depends on what one is looking for, because to me Windows feels the most dated of any desktop environment mainly due to its poor implementation of virtual desktops.
Even the version of Spaces from OS X 10.5 Leopard (circa 2007) is better, and various *nix DEs had better virtual desktops since the mid-late 90s onward. That makes Windows harder to use for me than lack of snapping on macOS does, particularly with how Windows makes me feel like I need to maximize most windows which drives a greater need for good virtual desktops.
What I miss most in macOS is the raw graphics performance of Windows, even for day-to-day computing. Probably a combo of available graphics cards, drivers, and how the OS treats graphics performance. Finder is def getting a bit creaky, but I've never hit limitations using it.
